6. Fit, but do not glue, the Tank Roof (TR)
followed by the Right Upper Crutch (RUC) and
Left Upper Crutch (LUC) into former F-1. Place
the assembly in its location on the plans between
the main stringers. Note: Left crutch is slightly
longer than the right crutch to set the engine
thrust angle.
7. Fit former F-2 to the upper crutches. Making
sure F-1 is perpendicular to the building board, use
medium CA to glue the TR, RUC and LUC to the
aft side only of F-1. Later we'll glue the parts to
the front of F-1 with a fillet of epoxy. Do not glue
the TR to the upper crutches forward of F-1.
Glue F-1 and F-2 to the side stringer and glue F-2
to the crutches.
NOTE: From this point on you will encounter a few
areas on the structure that may be difficult to glue
because they are not easily accessible. At this
early stage much of the structure only needs to be
tack glued, but it can be reinforced with thick or
medium CA after the sheeting is applied and the
frame is removed from the building board.
8. Drill 3/16" holes through the punch marks in
formers F-7 and F-8. With the numbers facing
forward, glue the remaining formers F-3 through
F-9 to the side stringers.
NOTE: Use a small triangle to hold ALL
formers vertical while gluing. Any small warps
or twists will be taken out when the 3/16"
stringers are glued in later.

9. Glue the two halves of the die-cut 1/8" balsa
Cockpit Deck together, then glue it to formers F-3,
F-4 and F-5. NOTE: If you will be installing the Top
Flite Scale Cockpit Interior, do not glue the cockpit
deck to F-4.

10. Glue the die-cut 1/8" plywood Stab Saddles
to F-9 and the side stringers. Note: The bottom
edges of the stab saddles are not flush with the
side stringer but set away from the outside edge
slightly. Also, the tops of the saddles are canted
toward each other.
RAZORBACK VERSION:
Perform steps 11, 12 and 13 only if building the
Razorback version.
11. Glue the die-cut 1/8" plywood formers IP, CB
and 5-C to the cockpit deck and former tops 6-C
and 7-C to their respective formers. Hint: If you
have decided to install the Top Flite Scale Cockpit
Interior, glue the IP to the cockpit deck from the
front only and CB from the back only. Most of the
cockpit deck will be cut flush with IP and CB.
NOTE: Save all the unused portions of the
